Technical Field

[0001] This utility model relates to the field of diamond testing technology, and in particular to a device for testing the mechanical properties of diamond. Background Technology

[0002] Diamond is the hardest known natural substance, possessing extremely high hardness, strength, and wear resistance, while also exhibiting excellent elastic modulus and fracture toughness. Currently, most diamonds are synthetically produced. To ensure that diamonds meet factory standards, their properties need to be tested after production. Among these tests, the impact resistance of diamonds directly affects their service life and safety under high-impact environments, and is one of the important indicators for evaluating diamond quality.

[0003] Existing testing equipment requires manual lifting of the impact weight to a specified height when testing the impact resistance of diamonds. At the same time, the weight of the impact weight is fixed and cannot be increased or decreased as needed. Utility Model Content

[0004] The purpose of this invention is to provide a diamond mechanical property testing device that can adsorb an impact counterweight to a specified height, thereby improving testing efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A diamond mechanical property testing device includes a testing bracket, a portal frame fixed on the testing bracket, an electric telescopic cylinder vertically downwardly mounted on the portal frame, and an electromagnet fixed on the piston rod of the electric telescopic cylinder. Two guide rods are vertically upward on the detection bracket. The guide rods are located inside the portal support frame. An impact support plate is slidably mounted on the guide rods. Several impact counterweights are detachably installed above the impact support plate. An impact protrusion is provided at the bottom of the impact support plate. An impact-bearing groove is provided on the detection bracket at a position opposite to the impact protrusion.

[0008] As an improvement, a guide limiting plate is fixed on the piston rod of the electric telescopic cylinder, and the guide limiting plate is slidably limited within the portal support frame.

[0009] As an improvement: a first positioning bracket is provided on the front side of the portal support frame, a first limiting cylinder is horizontally provided on the first positioning bracket, and a first positioning plate is fixed on the piston rod of the first limiting cylinder; A second positioning bracket is provided on the rear side of the portal support frame, a second limiting cylinder is horizontally provided on the second positioning bracket, and a second positioning plate is fixed on the piston rod of the second limiting cylinder.

[0010] In summary, this utility model has the following beneficial effects: 1. The impact counterweight and impact support plate can be attracted by an electromagnet. The electromagnet can be adjusted in height according to experimental needs under the action of an electric telescopic cylinder, eliminating the need for manual lifting and improving testing efficiency. 2.

[0014] Please refer to Figures 1-3 A diamond mechanical property testing device includes a testing bracket 1, a portal frame 2 fixed on the testing bracket 1, an electric telescopic cylinder 3 vertically downward on the portal frame 2, and an electromagnet 4 fixed on the piston rod of the electric telescopic cylinder 3. Two guide rods 5 are vertically upward on the detection bracket 1. The guide rods 5 are located inside the portal support frame 2. An impact support plate 6 is slidably mounted on the guide rods 5. Several impact counterweights 7 are detachably installed above the impact support plate 6. An impact protrusion 8 is provided at the bottom of the impact support plate 6. An impact-bearing groove 9 is provided on the detection bracket 1 at a position opposite to the impact protrusion 8.

[0015] In this embodiment, the impact counterweight 7 and the impact support plate 6 can be attracted by the electromagnet 4. The electromagnet 4 can be adjusted in height according to experimental needs under the action of the electric telescopic cylinder 3, without the need for manual lifting, thus improving the detection efficiency.

[0016] Furthermore, the impact support plate 6 and the impact counterweight 7 are both made of materials that can be attracted by the electromagnet 4.

[0017] Two threaded grooves 10 are formed on the impact support plate 6, and a first through hole 11 is formed at the top of the threaded grooves 10. A second through hole 12 is formed on the impact counterweight 7 at a position opposite to the first through hole 11. A connecting stud 13 is inserted into the threaded grooves 10, the first through hole 11, and the second through hole 12, and a connecting nut 14 is detachably screwed onto the top of the connecting stud 13. In this embodiment, the impact counterweight 7 is detachably mounted on the impact support plate 6 via the connecting stud 13, and can be added or removed as needed, improving the applicability of the test.

[0018] A guide limiting plate 15 is fixed on the piston rod of the electric telescopic cylinder 3, and the guide limiting plate 15 is slidably limited within the portal support frame 2. In this embodiment, the guide limiting plate 15 can improve transmission stability.

[0019] A first positioning bracket 16 is provided on the front side of the portal frame 2, and a first limiting cylinder 18 is horizontally provided on the first positioning bracket 16. A first positioning plate 20 is fixed on the piston rod of the first limiting cylinder 18. A second positioning bracket 17 is provided on the rear side of the portal frame 2, and a second limiting cylinder 19 is horizontally provided on the second positioning bracket 17. A second positioning plate 21 is fixed on the piston rod of the second limiting cylinder 19. In this embodiment, the two limiting plates can be used to replace the impact counterweight 7 and support the impact support plate 6, thereby facilitating replacement.

[0020] In this embodiment, a control panel 22 is provided on the portal support frame 2. The control panel 22 is used to control the operation of the first limit cylinder 18, the second limit cylinder 19, the electric telescopic cylinder 3, and the electromagnet 4. This is prior art and will not be described again. The first limit cylinder 18, the second limit cylinder 19, and the electric telescopic cylinder 3 are all integrated electric cylinders. A distance sensor 23 is provided above the material impact docking groove 9. The distance sensor 23 is connected to the control panel 22.

[0021] Working principle: Insert the docking stud 13 into the threaded docking groove 10, the first docking through hole 11, and the second docking through hole 12, and insert the impact counterweight 7 on the docking stud 13 as needed for testing.

[0022] After the addition or reduction is completed, the electromagnet 4 attracts the top impact counterweight 7, and the diamond to be tested is placed into the material bearing impact docking groove 9. The first limit cylinder 18 and the second limit cylinder 19 are activated to release the first positioning plate 20 and the second positioning plate 21 from the limit support of the impact support plate 6.

[0023] The height of the impact support plate 6 is adjusted by the electric telescopic cylinder 3. After reaching the specified height, the electromagnet 4 releases the impact counterweight 7. The impact counterweight 7 and the impact support plate 6 move downward under the action of the guide rod 5. The impact protrusion 8 accurately impacts the diamond in the material bearing impact docking groove 9, and the test is completed.

[0024] When it is necessary to add or remove the impact counterweight 7, the electromagnet 4, under the action of the electric telescopic cylinder 3, attracts the impact counterweight 7 and the impact support plate 6 to move above the first positioning plate 20 and the second positioning plate 21.

[0025] Activating the first limit cylinder 18 and the second limit cylinder 19 moves the first positioning plate 20 and the second positioning plate 21 to below the impact support plate 6, respectively. The electromagnet 4 is released from its attraction, and the docking nut 14 is unscrewed from the docking stud 13, allowing the impact counterweight 7 to be added or removed.
